Answer:
a. [tex]\frac{4a}{15}[/tex]
b. $225
Step-by-step explanation:
Let Mr. Scruggs got money for his birthday be 'a'
He spent [tex]\frac{1}{5}[/tex] of it on dog treats = a × [tex]\frac{1}{5}[/tex]
= [tex]\frac{1}{5}a[/tex]
remainder amount would be = a - [tex]\frac{1}{5}a[/tex]
= [tex]\frac{4a}{5}[/tex]
Then he divided the remainder money equally among 3 favorite charities.
[tex]\frac{\frac{4a}{5}}{3}[/tex]
= [tex]\frac{4a}{15}[/tex]
a. Each charity receive [tex]\frac{4a}{15}[/tex]
b. If he donated $60 to each charity.
[tex]\frac{4a}{15}=60[/tex]
[tex]a=\frac{15\times 60}{4}[/tex]
a = $225
Mr. Scruggs received $225 for his birthday.
